CHARLES T. HOLLOWAY, OF BALTIMORE, MARYLAND.

CHEMICAL FIRE-ENGINE.

SPECIFICATION forming part of Letters Patent No. 493,028, dated March 7,1893. Application filed December 17, 1891- Serial No. 415,354. (Nomodel.)

To all whom it may concern.-

Be it known that I, CHARLES T. HOLLOWAY, a citizen of the United States,residing at Baltimore, Maryland, have invented certain new and usefulImprovements in Chemical Fire- Engines, of which the following is aspecification.

This invention relates to an improvement in chemical fire engines, andthe object is to provide a front and rear discharge from the tanks bothcontrolled from the rear end of the engine.

To this endthe invention may be said to consist in the novel features ofconstruction and combinations of parts hereinafter described andclaimed.

The invention is illustrated in the accompanying drawings, in which,

Figure 1 is a longitudinal section through the middle of the engine;Fig. 2, a rear end View without the wheels, springs, &c.; Fig. 3, anenlarged outside view of a valve which is located at the junction of thedischarge-pipes; and Figs. 4, 5, 6, and 7, section views of said valveshowing its different positions.

The letter, A, designates the tanks of the engine, which are providedwith the usual appurtenances. Out of the rear end of each tank extends apipe, B, and these two pipes are connected by a four-way coupling, D, atthe middle. A discharge-pipe, E, extends downward from this coupling andthence forward and again downward to a hose-basket, F, adjoining therear step, G. Another discharge-pipe, H, extends from the coupling, D,first upward and then forward to the front of the engine where it entersthe hollow axle, I, of a hose-reel located behind the front seat, J.

In the coupling, D, is a rotary plug-valve, K, having anumber ofpassages, a, b, b, c. The

single passage, a, is arranged to form a communication between any twoadjacent pipes leading into the coupling; the two similar passages, b,b, are arranged to form communications between two pairs of adjacentpipes at the same time; and the branching double passage, c, is arrangedto form communication between any three pipes. The closed position ofthe valve is as shown in Figs. 3 and 4, when all the pipes are cut out.When it is desired to discharge from either tank K into one of thedischarge pipes the valve is turned to put the passage, a, intocommunication with I the tank and discharge pipes the other pipesremaining cut out, as shown in Fig. 5. When it is desired to dischargefrom both tanks into separate discharge pipes the valve is turned tobring the passages, 19, b,'into communication with the tank anddischarge pipes, as shown in Fig. 6. Whenit is desired to discharge fromboth tanks into one pipe or from one tank into both discharge pipes, thevalve is turned to bring the branching double passage, c, intocommunication with the tank.

and discharge pipes, as shown in Fig. 7. The

cook or valve, K, has a suitable handle, K,

by means of which it is shifted, and on the outside of the valve thepassages are traced as illustrated in Fig. 3, to show their position atdifferent adjustments of the valve. Each pipe is provided with anordinary cock, B,

E, H, which cocks serve as additional means for governing the discharge.By my arrangement as herein described one attendant at the rear end ofthe engine can control both the'front and rear discharges.

Having thus described my invention,what I claim as new, and desire tosecure by Letters Patent, is

In a chemical engine the combination of a pair of tanks; a pipe leadingout of the rear rear dischargepipe extending downward from said couplingto connect with the hose carried at the rear end of the engine; a frontdischarge-pipe extending forward from said coupling to connect with hosecarried at the front of the engine; and a cook or valve in said couplinghaving passages so arranged that communication may be had between anytwo adjacent pipes, between two pairs of adjacent pipes, or between anythree pipes, substantially in the manner described.

In testimony whereof I affix my signature in the presence of twowitnesses.
